Abstract
A fluorescent material includes at least one fluorescent compound having a structure formula of ABXYas defined in the specification, a plurality of NHgroup-containing ions bound to the fluorescent compound through protonation of amine groups of an amine composition, and a plurality of COOgroup-containing ions bound to the fluorescent compound through deprotonation of carboxyl groups of an acid composition. The amine composition has a total hydrogen bonding Hansen solubility parameter (Tδ) ranges from 2.4 to 3.3 (cal/cm), and the acid composition has a total polar Hansen solubility parameter (Tδ) which is less than 1.4 (cal/cm).
